QARD-EXHlBlTCR.

SPECIFICATION forming part of Letters Patent No. 378,345, dated February21, 1888.

-Application filed September 21, 1887. Serial No. 250,362. (No model.)

To all whom it may concern.-

Be it known that LWALTER D.VALENTINE,

of the city and county of San Francisco, and

State of California, have invented an Improvement in Gard-Exhibitors;and I hereby declare the following to be a full, clear, and exactdescription thereof.

M y invention relates to that class of machines for exhibiting cards inwhich the cards are contained in a hollow column or tube, and aresuccessively forced out by a slide into a holder, said holder having amovement by which it is placed in position to receive the card, and,after exposing, to discharge it; and my invention consists in the novelpushingslide and attached card-support, and the mech anism for operatingsaid slide, the movable card-holder and the mechanism for operating it,the alarm apparatus, and governing device for controlling the operationof the machine, all of which I shall hereinafter fully describe.

The object of my invention is to provide a simple and effective machinefor automatically exhibiting cards of any description successively andat suitable periods.

Referring to the accompanying drawings, Figure 1 is a perspective viewof my machine. Fig. 2 is a vertical longitudinal section on the line a:v of Fig. 1. Fig. 3 is a cross-section on line 9' y, Fig. 2. Fig. 4 isa vertical section of disk U of the governor, the fly-wheel being inelevation. Fig. 5 is a cross-section of the governor on the line 3/ 3/of Fig. 1.

A is the frame of the machine, upon the top a of which is supported thehollow column or casing B, in which the cards are contained in verticalseries, and having, if desirable, a superincumbent weight, W. The cardsare put in from the top of the column, or, if preferable, from the side,for which purpose I make a sliding door, I), in one side of the column.The lower edges of the front and back walls of the column do not comequite down to the top of the frame, so that they leave an opening orspace, 0, between their lower edges and the top of the table, theforward opening being for the purpose of allowing the card to pass outof the column forwardly, and the rear opening being for the purpose ofallowing the pushing'slide to pass into the base of the colthe column,and beyond the forward edge of the slide far enough to always remainunder the card being pushed out until the slide retracts, when itwithdraws from under the card.

F is the card-holder, consisting of an open frame work adapted toreceive the card through its back and to discharge it through its front,as will hereinafter more fully appear.

The card-holder is secured at its forward edge to an oscillating shaft,G, mounted in the frame A, so that said holder may turn with the shaftas an axis from a horizontal position, in which it lies backwardly andin line with the opening 0 in the base of the column, to a verticalposition, in which its open base is in line with a guide-chute, H, whichterminates in a receiving-troughJ. To the frame A,and just in front ofthe forward edge of the cardholder, is secured a small bracket, J, whichis for the purpose of preventing the card, when first pushed into theholder, from moving too far, though it in no wise prevents the card fromdropping through theholder at the proper time, as it consists simply ofan arm or arms, and not of a complete trough.

K is a gong, and 7a is the hammer which is adapted to strike it,saidhammer having a. stem, k, secured to a spring-controlled shaft, 76",on which is loosely pivoted a downwardlyextending crank-arm, is, havinga pin, It, on which the hammer-stem rests normally.

Upon the rear edge of the pushing-slide D is a small lug, L, which, whenthe slide is moving} forward into the column B and pushin g out a card,slips by the crank-arm 7c, causing it to move freely without affectin gthe hammer; but on the return-stroke this lug, coming in contact withthe forward edge of the arm, causes it, through its pin it, to raise thehammer, and as it slips by to drop it again, so that the alarm issounded.

The mechanism for operating the several parts is as follows:

M is a drive-shaft,over a grooved pulley, m,

V on the end of which is passed the driving belt cular, but having atone side the eccentric or a cam portions, as is shown in Fig. 2.

Q is a lever, the upper end of which engages a bracket, d,on the base ofthe pushingslide D, and the lower end is pivoted at q, said lever beingprovided with a stud, g, which fits in the cam-groove 19. To theoscillating shaft G of the card-holder F is attached a crank, R, fromwhich a link, 7', extends to a lever, S, the lower end of which ispivoted to a center at s, and is provided with a stud, s, which fits inthe cam-groove p on the other side of the worm-gear P. By theseconnections the pnshing-slideis moved back and forth and the cardholderoscillated.

The operation of the machine as far as described is as follows: Thecards being placed in vertical series in the hollow column, the motivepower is started, so as to rotate the shaft M, thereby, through its wormO, rotating in the direction shown by the arrows the wormgear P, havingthe cam-grooves p p on its opposite sides. Referring to Fig. 2, theinterrelationship or timing of these cam-grooves will be seen to be asfollows: The normal position of the pushing-slide D is forward withinthe tube, and the normal position of the cardholder F is elevated, sothat the card it contains is exposed to view, and has its lower edgeresting on the projected front of the card-supporting plate E,which isattached to the slide D, Fig. 1. These positions are maintainedthroughout the entire circular or concentric portions of bothcam-grooves, so that the viewers have a chance to observe the card foran appreciable period of time, while said card is properly supported inthe holder. The first efi'ect which now takes place is caused by theinturned portion of the cam-groove 19 coming up with the stud q of thelever Q,whereby said lever is forced backwardly, thereby immediatelywithdrawing the supporting-plate E from under the card, so that it dropsdown into the receiving-trough below, and the slide itself moving back,its lug L comes in contact with the arm lciwhich operates thegong-hammer, thereby giving notice of the operation and the immediateprospect of a fresh card. While the slide 1) is moving back, anddirectly after the supporting-plate E withdraws from under the card, theoutturned portion of the cam-groove p,coming up with the stud s, forcesthe lever S forward,which, through the link r and the oscillatingcrank-shaft G, causes the card-holder F to move backwardly to a thecam-groovep. As soon as the card is well in the holder and thesupporting-plate E is moved forward to position, the inturned portion ofthe cam-groove p now forces the lever S back, which movement effects theuprising of the card-holder to its first position, and all the partsthereupon remain inactive during the passage of the concentric orcircular portions of both cam-grooves.

In order to control and govern the speed of the machine, I have thefollowing device: On the end of the drive-shaft M is secured a flywheel,T, and to the boxing mof said shaft is firmly secured a disk, U, havinga rim-flange, a, which projects inwardly under the inner circumferenceof the rim t of the fly-wheel, though without touching it, so that itdoes not interfere with the rotation of the wheel.

By referring to Fig. 5 it will be seen that the fly-wheel is made with adishshaped inner portion, and that the disk U is of a cup shape, fittingthe cavity of the fly-wheel, and by making the back of said disk of thesame shape or contour as the front of the fly-wheel the two parts fittogether in such a way as not to be noticeable, the whole appearingsimply as a fly-wheel, though the disk, being fast on the box, does notrotate. Secured to the inner face of the fly-wheel, and extending intothe space between the body of the wheel and the disk, are slotted lugsV, in which are fitted curved springs X, having on one end brakeshoesas, which impinge against the inner surfaceof the flange a of the fixeddisk, and said springs are secured in the slotted lugs by means ofset-screws 00'. Now it will be seen that when the motion of thefiy-wheel is increased the brake-shoes are thrown outwardly into greaterfrictional contact with the fixed flange of the disk, thereby serving tocheck the speed of the machine. springs by means of the screws thiseffect may be suitably regulated.

In a former application, Serial N 0. 225,403, for similar improvementsmade by me jointly with Howard S. Bailey, 1 have claimed, broadly, anymeans for operating the reciprocating follower, showing and describingmutilated gears and pinions as one means for inrparting the necessarymovements to the follower. I therefore do not claim in this appli- Byadjusting the cation the follower and any means for opcrating it, butlimit myself to the specific mechanism herein shown, described, andclaimed.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is
